I have a record defined like this:
-record(tick_data, {
symbol,
date,
ticks % tuple
}).
I create the table like this:
mnesia:create_table(tick_data,
[
{disc_copies, Nodes},
{index, [date]},
{type, set},
{attributes, record_info(fields, tick_data)}
])
My intent is to have a table where multiple records with the same
symbol but different dates can coexist. Will the above work or do I
need to create a bag table?
In other words, does Mnesia expect uniqueness on each keys or do both
keys work as a composite?
Thanks, Joel
